Some features like GPS free navigation is good. You can load the maps offline and use it without internet.
WLAN is not very good. It detects very less signals when compared to a Laptop. The devices comes with RAM of 128 which is very low and inbuilt memory of 81MB .
Good thing is that it have 8GB card.
The RAM gets fully occupied (overloaded) if you open 2 or more havy weight apps like Maps/ Games and reboots automatically when there is low RAM. Sometimes the phone gets hanged and there is no other go to hard reboot by removing the battery. It is best for those who use the inbuilt SW and the facilities when you go on adding the new widgets / applications performance degrades.
